BOX-NAILING MACHINE.

SPECIFIGATION'forming part of Letters Patent Ni556,430, dated. March 17, 1896.

Application filed April 12, 1895.

To all whom it may concern:

Be it known that I, HENRY WV. MORGAN, of

Rochester, in the county of Monroe'and State of New York, have invented certain new and to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

My present invention has for its object to provide an improved machine for nailing boxes; and it consists in certain improvem cuts and combinations of parts, all as will be hereinafter fully described and the novel features pointed out particularly in the claims at the end of this specification.

In the drawings, Figure 1 is a front elevation of my improved machine; Fig. 2, a side elevation of the same; Fig. 0, a top plan view; Fig. 4, a plan-view of the nail feeder or selector; Fig. 4, a section on the line a b of Fig. 6; Fig. 5, a vertical sectional view of the machine; Fig. 6, a similar View of the upper part considerably enlarged; Fig.7, a hori-' zontal section taken on the line :20 0c of Fig. 5; Fig. 8, avertical section on the line '3 'y of Fig. 6.

Similar reference numerals in the'several figures indicate similar parts.

The main frame of the machine (indicated by 1) may be constructed of one or of several parts suitably bolted together, and arranged upon the front thereof is the box support or table 2, guided upon the sides of the main frame and vertically adjustable, being provided with a rearwardly-extending bracket or lug through which passes an adjustingscrew 3 supported at its lower end in the main frame and having at its upper end a beveled pinion 4, with which latter meshes apinion 5 on a shaft 6, provided with a handwheel 7, the rotation of said hand-wheel serving to raise or lower the table, as will be understood.

The frame carrying the drivers embodies the side brackets or castings 8, sliding on guides formed on the main frame and connected by a back piece or plate 9, to which is pivoted one end of a pitman 10, the other Serial No. 545,544. (No model.)-

end being-connected to a crank 11, formed in a shaft 12, journaled in the lower portion of the -main-frame.- Upon said shaft is a gear 13, meshing with a gear 14 on a shaft 15,- also journaled in saidframe, and meshing with the gear 14 is a gear'16 on a shaft 17, with shaft 19 being continuously rotated and the" clutch operating to connect the'pinion therewith.

indicates cross bars connecting the brackets 8 and having the T-shaped slots in their under sides, in which operate the heads of the nail-drivers 24, said drivers being adjustable in the bars, so that they may-be moved by hand directly over the nail-holding jaws in the chucks, as presently described.

Arranged at the upper portion of the main frame and attached to suitable brackets thereon is a cross-piece25 having a number of nail-channels 26 therein corresponding to the greatest number of nails adapted to be driven at once by the machine, eight being shown in the present instance, and each of these channels has an a erture 27 in the to of the cross-piece and a narrow curved passage 28, extending around to the rear and communicating with the nail-channels 29 formed between plates 30 attached to an angular slotted cross-bar 31 connected to brackets 32 011 the upper portion of the frame,

The nails to be driven pass down the channels 29 and are removed from the lower end thereof and dropped into the aperture 27 by the rotary nail-selectors, one being provided for each nail-channel. These selectors each consist of a rotary disk 33 having a stud 34 operating in a suitable bearing-aperture in the cross-bar 25, and arranged on opposite sides of the disk are two vertical nail-receiving recesses 36 36 adapted, as the selectors are rotated in the direction indicated by the arrow in Fig. 4, to carry the lowermost nails in the channel 29 around, their heads being supported on the selectors, and deposit them in the recesses27, one nail, being carried around and deposited at each half,-.re volution of the selecting-disk under normal circumstances; but as it is desirable to regulate the number of nails delivered to the driving devices Iprovide upon the upper side of each of the selectors a movable disk or gate 37 journaled upona central stud 38 and having on one side of its periphery two recesses 39 and =i0 arranged to co-operate with the recess 36, and upon the other side of said disk I provide recesses 41 and 42, the relative ar-- rangeinent being such that when-therecess 39 is in line with the recess 36 the other recess, 36 is closed by the solid portion of the disk, thereby feeding but one nail at each complete revolution ofthe: selector. 1 \Vheu the recess-.42 is in line with the other recess,

36 ,in the selector, the opposite recess,.36, is closed, thereby feeding one nailat (3301100111:

plete revolution of theselector, but from the; recess 36* thereof opposite to the .one'first: mentioned, and when the-recess 40in the disk is in linewith the recess 36 the opposite re:

cess, 4:1,:registers with the othcrrecess,-36 so that one nail will be fedat each half-rotation of theselector, and, further, the diskcan be turnedvto close both of the recesses 36 36 and, no nail-will be fed during the rotation of the,

selector, this arrangement permitting anyof the selectors .to be thrown out of operation when desired.

As a means for fastening the gate in anyof the positions described, I. provide upon the gage with "anyone of a series of aperturesl in sai dpdisk, and I hold-the parts, in adjusted position bya cylindrical nut 45.: These .selectors may, be operated simultaneously .by

any suitable means; but I prefer :to arrange upon theupper side of eachqone of them a. wrist-pin, a6 passingthrough a suitable slot L7 in thegate-37 ,1whichpins eo-operate with a suitable connecting-bar 48 common to all;

of them, and having-its ends bent toward the rear of the machine andjournalediuponiwristpins 49 secured to the upper endsof each of two vertical shafts 150 arranged in brackets 51 on themain frame, thelower ends of said shaftshaving. beveled; pinions 52 aneshing with corresponding-pinions 53 on the extreme ends of shaft 15, and; as said shaft15 is given a half-revolution at eachoperation of the mar,

chinethe shafts 51 will each be givena halfrevolution, and through the; means just described the nail-selectors as well will be op erated. a

Connected to the underside of i the cross;

bar-Q5 is a serieswof nail-conveying chutes or tubes; 60,- eaeh: pivoted at, the front upon a screw or pinGl andadapted to convey thenails from thenail-channels 26 to themailsholding chucks arranged below, said chutes havinga; universal movement on said pins, so that the; nailswill ,be iproperly guided to the chucks whether the latter are in line or otherwise,-as shown.

The chucks62 for holding the nails are providedwith suitable inclined nail-channels 63 and with vertical channels 64, in which the drivers 24: operate, as shown particularly in Fig. 6, the lower end of the driver channel .having nail-holding jaws G5, pivoted at (if;

and operated toward each other by springs 67, the proximate-faces of the jaws being grooved for the shanks of the nails, holding them straight, so that as the nails pass down into the chucks they will be held between said jaws in position to be operated upon by thedrivers when the latter are brought down.

Inasmuch as it is desirable to drive the nails simultaneously-in the sides and end pieces of the box, as shown, for instance, in

' dotted lines in Fig. 7, I construct the chucks so that they are all interchangeable and capable of beingreversed on'their support, said support eonsistingzin the presentvinstance oil two-cross-bars. 68 secured to brackets 69 on the main frame; andthegchueks are each pro: vided with a stud; 70 fitting the space he-, tweenisaidbars, and having at its outerend a threaded extension upon which is arranged a clamping-nut 71.1501 holding said chucks SC? curely in position.

The proximate faces of the jaws of the chucks are grooved, as stated, so that whennailsdrop down into them they 1 are maintainedv in upright position and sus tained for a considerable distance below the headin order that they maybe driven straight into the box withoutliability of being iniproperly positioned. shown two :outer nail-chucks::arranged for- In the drawings 1 have a ward of the others,the,lower ends of the nailchutes 0O resting in the upper ends of the chutes or channels 63, thusdelivering the Byaiw ran gingn the support for the chucks between i thenail-driver supports it will be. seen that thechucks can be arranged to drive nails in i the, end pieces of the box at thesaine time with-those in theisides and this wit-houtemploying curved chutes, in which the nails nails properly from the feeddevices.

might become clogged. This construction is also advantageous in connection with adj ustableselectors, as it is desirablesometimes to position the nailsdifferently ondiiferent sides or on theends of the box, and thisinay therefore beaccomplished'by my construction The nails are contained in theusual tilting nailreceptacle81 pivoted at, 82 to the hrack ets32, andnsaidreceptacle is provided in its bottom with the usual grooves and slots or i channels 272, which register with the slots or channels 29, and theireceptacle is adaptedto be :tiltedby means of a pi'tinan 73 pivoted to its 'under side and connected to a wristrpinw 74 on a gearor disk on the shaft 17, as shown particularly in Fig. 5, the construction being such that when the receptacle is in the posi-; ;tion shown in Figs. 2, 5and 6 in full: lines thenailswill gravitatetoward the lower front heads, as usual.

; end and their shanks will pass down through. the slots,: being; sustained by the enlarged.

In order to prevent all of the nails from sliding down to the front of the receptaclewhen the latter is raised and thereby preventin g proper movement of those in the channels or slots I arrange within said receptacle a rod 7 constituting a gate, connected to arms 89,

. pivoted at 76, and adapted when the'receptacle is in the position in full lines to rest against studs 77 so that a comparatively small portion of the nails can fall over the bar to the front, but when the receptacle moves down to the position shown in dotted lines in Fig. 6 all of the nails in the front except those contained in the channels will fall back to the lower end of the box, the gate maintaining its vertical position, as shown, this device preventing more than a limited quantity from falling to the forward end of the box, as will be understood.

In the operation of the machine the box to which the bottom or cover is to be nailed is arranged upon the table 2, which has been adjusted to the proper height to bring the upper edge of said box close beneath the chucks, and the box is positioned rearwardly and laterally by means of a bar 78 having an adjustable stop 7 9 thereon and adapted to be moved backward and forward by means of screws 80, as shown particularly in Fig. 7.

Assuming the position of the disks or gates 37 on the selectors to be that shown in Fig.

tion,carrying the nails retained in the recesses 36 36 in the selectors around and depositing them in the channels 27, from which they pass to the holding-jaws in the chucks, as will be understood, and are ready to be driven at the next operation of the machine. The nail pan or receptacle during this operation falls to the position shown in dotted lines in Fig. 6, the gate dropping back relatively and permitting the backward passage of the nails.

The construction of the selectors and the gates therefor is desirable in a machine of this description, as it sometimes happens that it is desirable in nailing boxes to drive the nails in, say, the second and fourth chucks when nailing the sides of the boxes, and the first, third and fifth when nailing the ends, and it will understood that by adjusting the gates on the selectors,as previously described, this can readily be accomplished,the selectors being adapted to feed one nail at each halfrevolution, or at either the first or second half of the revolution of the selector, or they may be permitted to turn without feeding any nail at all, as the gates thereon are adjusted. The

construction of this gate may be'modified or otherwise constructed to accomplish the same result, and I do not desire to :be confined to exactly the construction shown, as I believe myself to be the first to provide a device of this description in a nailing-machine.

The selectors are all constructed alike and as well as the chucks are interchangeable,so that the parts of the machine are few and repairs can be easily and cheaply made to the operating parts when required. I It will be understood that it is not essential to give the selectors a half-rotation at each operation of the machine, but it is sufficientif the recesses are brought alternately in engagement-with the ends of the nail-channels and the apertures 27, so that if they vibrated or slid or oscillated the result would be accomplished.

The particular-form of clutch device controlled by the foot-lever 21 is immaterial as far as my present invention is concerned and may be such as are in use in machines of this description, or preferably such as shown in Letters Patent No. 496,431, granted to me May 2, 1893, for improvements in box-machines.

Instead of forming only two recesses in each selector any number-could be employed and the operating means arranged to give them a rotation or movement equal to the distance between the proximate ones, the gates being employed to cut off any or all as desired.
